Therefore, if there is snow on a power transmission line, it is necessary to constantly monitor the mat and, if a certain amount of snow is detected, to stop power transmission on the power line and perform snow melting work. In addition, for the power transmission lines and electricity stations that make up the power system, loose operation is common in which multiple circuits and multiple transmission lines are used in succession between each electricity station (although this has been done twice, in this case If the target power transmission line is stopped for the sole purpose of snow melting, the tide flow within the system will change, and it is possible that overload will occur in the system equipment.Therefore, when stopping the target power transmission line, it is necessary to prevent overload from occurring. It is necessary to take this into consideration in advance.
